The Tektronix 672-2045-05 Acquisition Board is a high-performance data acquisition component engineered for precise waveform capture and analysis in oscilloscope systems. This two-channel acquisition module delivers 8-bit vertical resolution with 1,000 samples per channel record length, supporting simultaneous signal acquisition across demanding test and measurement applications.
Technical Specifications
• Channels: 2 input channels with simultaneous acquisition
• Record Length: 1,000 samples per channel
• Vertical Resolution: 8-bit
• Horizontal Sweep Time Base (A): 1 s/division to 10 ns/division in 1-2-5 sequence (25 steps); extends to 1 ns/division with X10 MAG
• Horizontal Sweep Time Base (B): 50 ms/division to 10 ns/division
• Input Coupling (DC, Channels 1–2): ±[3% of setting + 3% of p-p signal + 0.2 division + (0.5 mV × probe attenuation factor)] at 15°C to +35°C
• Input Coupling (NOISE REJ, Channels 1–2): Add ±0.6 division to DC coupled specification
